Air Pollution

Weather forecast maps indicate that “due to the atmosphere stability and stillness” in the northern half of the country till Thursday, increase in the density of pollutants will occur in industrial cities including Tehran, Isfahan, Arak, Karaj, Tabriz and Mashhad. Decline in air quality can reduce horizontal visibility, Mehr News Agency quoted Ahad Vazifeh, head of the Iran Meteorological Organization’s Early Warning Unit, as saying.
